President Joe Biden warns of the dangers of oligarchy and the tech industrial complex in his final Oval Office speech. He highlights the concentration of wealth in the US and the erosion of democracy due to misinformation and disinformation. Biden's legacy has been overshadowed by the return of Donald Trump to power and the Democratic Party's lack of leverage in national politics. Despite overseeing a recovering economy and addressing issues such as COVID-19 and climate change, Biden was unable to heal divisions in the country or prevent democratic backsliding. His achievements may be overshadowed by Trump's resurgence.
